The system board supports up to 12 Gbyte main memory. 6 slots (3 memory
banks with 2 modules) are available for the main memory. Each memory bank
can be populated with two 256, 512 Mbyte, 1 Gbyte or 2 Gbyte registered DDR
333 (PC2700) memory modules.
A memory bank can be configured as hot spare bank (optional).
As in the basic configuration memory bank 2 is populated with 512 MB, 1 Gbyte,
2 Gbyte or 4 Gbyte memory modules, the memory extensions can be
performed up to two times for memory bank 1 and 0.
ECC with memory scrubbing and with the Single Device Data Correction
